COTTON-CHOPPER.

SPECIFICATION forming part of Letters Patent No. 343,140, dated June1,1886. Application filed September 22, 1885. Serial No. 1715 0 1. (Nomodel.)

To all whom it may concern.-

Be it known that I, WILLIAM H. RICHARD- soN, of the city ofBaltimore,and State of Maryland, have invented certain Improvements 1nCotton-Choppers, of which the following is a specification.

In the description of the said invention which follows reference is madeto the accompanying drawings, forming a part hereof,in which Figure I isan exterior side view of the invention; Fig. II, an end view of thesame, and Fig. III, a section of Fig. I, taken on the dotted line :0Figs. IV, V, VI, and VII are details of the invention, as hereinafterdescribed.

A is the standard, a portion only of which is shown in the drawings.

B is the plow-beam, and O the plowshare, fastened to the standard A.

D is the guard-plate, pivoted to the standard at a, and attached to theplowshare at b. By removing the bolt at b the plate D may be turned upand rendered inoperative, as shown in dotted lines, Fig. I.

E is a skeleton cylindrical drum, formed of the heads a, which arefastened to the square shaft d, and the bars 6, bolted to the heads.

F F are hoes, bolted to shanks f, which pass through slots 9 in the barsc and the square shaft d. The shanks f of the opposite hoes lap eachother, and are held firmly in position by means of set-screws h. (Seeparticularly Fig. III.) The bars 6 and the square shaft (1 have a numberof unoccupied slots, g, in order that the positions of the several hoesmay be changed at pleasure or others added. The square shaft (1 isprovided with circular grooved collars G, keyed thereto, as shownparticularly in Figs. IV and V, and these collars serve as bearings forthe shaft and can be made as large as required.

H are hangers for the shaft (1, and they consist of bars with eyes orcircular straps at their lower ends, which fit over the grooved parts ofthe collars G. These collars are made in two parts or sections boltedtogether, as shown in Fig. IV, in order to admit of the eyes or strapsof the hangers H being used without a break. The hangers pass throughthe beam B, and are secured to the beam near to its end.

I is a bracket, secured to the beam B near to its end by means ofset-screws j. In order that the bracket I can be readily applied to thebeam 13, it is made with eyes k, through which the beam is passed. (SeeFigs. I and II.) The bracket I terminates at its lower end in a lug, I,from which extends a supportingpiece, m, for the end of the shaft d.

K is a stud, fastened in the lug Z, on which the wheel L turns freely.vided with spuds a at its periphery, adapted to enter the ground as themachine is propelled, and it has a beveled gear, M, secured to its innerface in any suitable manner.

N is a beveled pinion, adapted to slide longitudinally of the shaft d,on which it rests. lVhen the pinion N is moved to the position shown inFig. I, it is in gear with the beveled wheel M, and it may be secured insuch position by means of the button 0, which hangs on the thumb-screw9. If desired, a spiral spring, q, (shown in Fig. VI,) may be usedbetween the pinion and the supporting-piece m, in order that when thebutton is thrown down the pinion will be moved back and out of gear withthe beveled wheel M. When the plow is forced forward,the revolution ofthe wheel L effects, through the medium of the gearing described, therotation of the hoes, and should the machine be drawn parallel with andnear to a row of cotton-plants the hoes chop out spaces and leave hills.The size of the hills, or rather the width of portion of the row removedby the hoes, can be regulated by the number and position of the hoes,which can be varied.

It will be seen that the hoe mechanism is removable, and may be appliedto any plow by merely boring two holes in the beam for the hangers H.Should the holes or eyes in the bracket I be too large, wooden linersmay be used to fill the extra space between the metal and the plow-beam.It will be further understood that the depth of cut of the hoes maybechanged by moving the shanks in or out, as required.

I claim as my invention- 1. In combination with the beam of a plow, theremovable bracket I, stud K, wheel L, adapted to turn loosely on thesaid stud, bevelcd gear M, fastened to the face of the wheel This wheelis pro- IOO L, shaft d, supported by hangers H H from the 2. Incombination with the plow-beam B, beam B, beveled pinion N on shaftd inengagethe shaft d, carrying the skeleton drum E,with IO ment with thebeveled gear M, drum E, formed its hoes F, the grooved collars G, andhangers of the headscand bars 6, extensible hoe-shanks H, substantiallyas specified,

f, which pass through the shaft d and the bars WILLIAM H. RICHARDSON. e,and means to secure them in place, and the Vitnesses: hoes F, attachedto the shanks f, substantially CHARLES W. ARNOLD,
